Description

  The present invention provides a umbilical cord that is a generic term for a string or a thread, in a umbilicus that extends from a cocoon of a cocoon fruit as an example of a shaft part in order to make a plurality of cocoon fruits as an example of an article having a shaft part. As an example, the present invention relates to a connecting device for sequentially tying knot yarns.

    Dried persimmons are made by peeling peeled ginger from string threads such as tako thread or hemp string and exposing them to the sun and drying them, or putting them in a dryer and drying them. At that time, a lot of ginger is hung in a good shape with a gap between one string thread (for example, tako thread, hemp string, etc.). This is done by repeatedly bundling the fruit-shaped fruit shafts in a solid manner such as “Tatari knot” which binds one string thread in a double entanglement manner.

  In this way, the method of binding the umbilicus, which is the fruit axis of each cocoon with the string thread, allows the operator to suspend it by adjusting the suspending interval as needed while visually checking the size and ripeness of the cocoon. Can do. In addition, once the string is tied to the navel, there is an advantage that the heel is unlikely to fall off the string, but on the other hand, the string is removed from the umbilical cord after drying, There is a problem in that it takes time and effort to recover the wrinkles after cutting.

  In particular, in the case of dried cocoons sold in circulation, it is necessary to completely remove the string from the dried cocoons and cut the navels to an appropriate length to adjust the appearance. Moreover, the work is concentrated on the time when the ginger is harvested and the time when the drying process is completed. In the work of collecting the firewood that has been collected, the number of firewood handled by the worker increases, and furthermore, each work requires a certain level of skill.

  Therefore, in recent years, many methods have been studied that do not require the skill of an operator and can suspend ginger in a goodwill shape in a simple and short time and easily recover the dried cocoon. .

  For example, Patent Document 1 discloses that a resin-made, substantially flat plate-like opening portion into which a umbilicus extending from a heel of the heel is inserted, and a groove formed by cutting in a substantially wedge shape downward from the opening portion. And a lifting tool body forming slit-like openings for imparting elastic force to the navel inserted into the groove, are attached to a string or the like at substantially equal intervals, and are used for fruit production. A method of suspending a ginger by forming a suspending tool and an operator inserting an umbilicus into the groove from the opening and holding the fruit shaft elastically by a slit-shaped opening is disclosed. Yes.

  In this way, the method of suspending the cocoon in a goodwill shape by sandwiching and holding the fruit axis with the slit-like opening is simple, and the cocoon after drying is moved from the slit-like opening toward the opening. Can be removed easily.

  However, the ability to easily remove the heel after drying treatment means that the umbilicus is easily released by applying some force during the work of tensioning the string thread or during drying. It also has the problem of dropping out. In addition, the suspender body of the fruit suspender for fruit production is made of resin, is designed to easily hold the navel, and is manufactured using a mold. There will be a cost. And in order to repeatedly use the fruit suspending tool and the suspending tool main body every year, maintenance such as cleaning, disinfection, and storage is also required.

In such a state, the navel C of the cocoon fruit P is loosely inserted into the recess 8 of the table body 6 facing the set position. At this time, the umbilical C of the cocoon fruit P is not set in any other recess 8 of the table body 6.

  Thus, when the umbilical C of the heel fruit P is loosely inserted into the recess 8 of the table body 6 facing the set position, the umbilical C of the heel fruit P pushes and swings the set switch lever 48, As a result, the light shielding portion 46 integral with the set switch lever 48 shields light from the light emitting element to the light receiving element of the photosensor 44. The release motor 36 is driven by this light shielding, and the latch member 30 rotates so as to hold the umbilical C of the heel P in the set position. The rotation of the latch member 30 is stopped when the light shielding portion 46 shields light from the light emitting element to the light receiving element of the photosensor 44. At the timing when the driving of the release motor 36 is stopped, the motor 14 is driven, the table main body 6 is rotated by 90 degrees, and the fruit P is transferred to the knot forming position. The driving of the motor 14 is stopped when the photo sensor 26 detects the notch 26 of the position detection disk 24.

  In this way, when the heel P in the set position is transferred to the knot forming position, the motors 98 and 104 for moving the X direction table 94 and the Y direction table 100 of the winding mechanism 84 are moved simultaneously or When selectively driven, first, the weft S is wound around the bobbin wall 126 of the bobbin mechanism 88 as shown in FIG. 32A.

  Thereafter, as shown in FIG. 32B, the X direction table 94 of the winding mechanism 84 is moved in the X direction so that the sleeve 108 pushes the shutter plate 128. Then, the sleeve 108 of the winding mechanism 84 extends the weft S along the bent portion 126a of the bobbin wall 126 so as to push the shutter plate 128 against the spring.

  Further, the Y-direction table 100 of the winding mechanism 84 is moved in the Y direction close to the table main body 6, and along the other side of the bobbin wall 126 in the vicinity of the winding mechanism 84 as shown in FIG. 32C. The tako thread S is extended. Thereafter, the sleeve 108 is passed along the lateral side of the umbilical C of the cocoon fruit P, and the weft S is extended to the lateral side of the umbilical C. At this time, when the sleeve 108 is detached, the shutter plate 128 is positioned on the Y-direction table 118 of the bobbin mechanism 88 by the action of the spring.

  Next, the X direction table 94 of the winding mechanism 84 is moved in the X direction which is opposite to the direction in which the sleeve 108 pushes the shutter plate 128. Then, as shown in FIG. 32D, the tako thread S starts to be wound around the outer circumference of the navel C of the cocoon P.

  Thereafter, the Y-direction table 100 of the winding mechanism 84 is moved in the Y direction substantially outward of the radial direction of the table main body 6, so that the weft S is applied to the navel C of the cocoon P as shown in FIG. 32E. Let it wind.

  Furthermore, in the vicinity of the umbilical C of the heel P, the X direction table 94 of the winding mechanism 84 is moved again in the X direction so that the sleeve 108 pushes the shutter plate 128. Then, as shown in FIG. 32F, the weft thread S is further wound around the navel C of the cocoon P.

  Thereafter, the Y-direction table 100 and the X-direction table 94 of the winding mechanism 84 are moved in the same direction as in FIGS. 32C and 32D, and the weft thread S is moved to the navel C of the cocoon P as shown in FIG. Make one complete turn. At this time, the sleeve 108 is largely separated from the umbilical C of the heel fruit P, and is positioned in the vicinity of the set position of the heel fruit P.

  During the above-described operation, when the shutter plate 128 is not pushed by the sleeve 108, the shutter plate 128 is positioned above the bobbin wall 126 by the action of the spring, and the tread thread S wound around the bobbin wall 126 does not come out upward. It has come to play a role of retaining.

  Further, as described above, the weft yarn S is fed out from the tension mechanism 138, but when the swing arm 150 is at the lowest position in the swing range, the weft yarn S is pulled out to the maximum length. As described above, when the knot is roughly formed, the pulled-out weft thread S is used, so that the swinging arm 150 swings upward and finally comes to the stopper 152. It will abut and stop.

  Next, the first loop of the weft S formed on the outer periphery of the bobbin wall 126 in order to form a knot around the navel C of the persimmon fruit P It is necessary to stack on the second loop.

  For this purpose, the Z-direction table 112 of the bobbin mechanism 88 is raised so that the first loop of the weft S formed on the outer periphery of the bobbin wall 126 is more than the second loop formed on the umbilical C of the heel P Position vertically above. In this state, the Y-direction table 118 of the bobbin mechanism 88 is advanced above the table body 6 as shown in FIG. 32H, and the bobbin wall 126 of the bobbin mechanism 88 is positioned directly above the navel C of the heel P .

  Then, the Y direction table 118 of the bobbin mechanism 88 is lowered, and the bobbin wall 126 around which the weft thread S of the bobbin mechanism 88 is wound is positioned on the outer periphery of the umbilical C of the heel P. Thereafter, the Y-direction table 118 of the bobbin mechanism 88 is retracted from above the table body 6 as shown in FIG. 32I. Then, the release claw member 134 causes the weft thread S wound around the outer periphery of the bobbin wall 126 to escape above the bobbin wall 126, and as a result, the weft thread S being tensioned by the tension mechanism 138 P is squeezed around the umbilical C and a knot is formed around the umbilicus C.

  As described above, the tension mechanism 136 swings the tension pulley 148 in the direction close to the driving pulley 142 and the driven pulley 146 while the knot S is formed on the outer periphery of the umbilical C of the cocoon P. The weft yarn S wound around the tension pulley 148 and bent so as to be moved is used so as to extend linearly. Finally, the driving pulley 142 and the driven pulley 146 are wound around the weft yarn S. Rotating in the direction of picking, the knot S on the outer periphery of the umbilical C of the cocoon fruit P makes the knot tight.

  As described above, when the knot S is formed on the outer circumference of the umbilical C of the first cocoon P, the table body 6 facing the set position with the umbilical C of the second cocoon P is set. It is loosely inserted into the recess 8. Then, the umbilical C of the second heel fruit P pushes the set switch lever 48, and the latch member 30 holds the umbilical C of the heel fruit P in the set position as described above. Then, the table main body 6 is rotated to transfer the cocoons P in the set position to the knot forming position.

  When the second cocoon P in the set position is transferred to the knot forming position, the weft S is already inserted into the sleeve 108 of the winding mechanism 84 at this stage. 84, the bobbin mechanism 88 and the tension mechanism 138 operate in relation to each other, and as described above, the knot C of the cocoon P in the knot-forming position is formed with a knot S to form a knot.

  At this time, a knot is formed by the tactile thread S, and the first cocoon P is at a position 90 degrees ahead of the knot forming position.

  Next, the umbilical C of the third heel fruit P is loosely inserted into the recess 8 of the table body 6 facing the set position. Then, the umbilical C of the third heel P pushes the set switch lever 48, and the latch member 30 holds the umbilical C of the heel P in the set position as described above. Then, the table main body 6 is rotated to transfer the cocoons P in the set position to the knot forming position.

  At the same time that the third cocoon fruit P in the set position is transferred to the knot-forming position, the first cocoon fruit P reaches the release position, and in this release position, the umbilicum of the cocoon fruit P The latch member 30 holding C releases the umbilical C of the heel P by driving the release motor 36. At this time, since the umbilical C of the three cocoon fruits P is sequentially connected by a single weft S, even if the umbilical C of the cocoon fruits P is released, the cocoon fruits are removed from the recesses 8 of the table body 6. The navel C of P will not fall off and fall.

  In such a state, the release lever 62 is driven by the drive of the release motor 36, and the pushing plate 70 pays the umbilical C of the first pail P from the concave portion 8 of the table body 6 to the outside. And store in a predetermined storage location.

  Next, the umbilical C of the fourth heel fruit P is loosely inserted into the recess 8 of the table body 6 facing the set position. In this way, when the number P of the cocoons P connected and connected one after another by a single weft thread S reaches a predetermined number, the motor 168 of the cutting mechanism 160 is driven and the table body 6 is driven. The cutter thread 164 extends from the cocoon fruit P located at the release position of the cocoon to the other recess 8 of the table main body 6 in the direction of the other cocoon fruit P where the umbilical C is closely located. Cut with.

  The fruit P of the other cocoon where the umbilical C is located in the other concave part 8 after the cut of the weft S and is tied together is the fruit of the next first cocoon.

  According to the above-described embodiment, it is only necessary to manually set the umbilical C of the cocoon fruit P in the recess 8 of the table body 6 at the set position, so that the preset number of cocoon fruit P is set to one. Since it can be tightly tied and firmly connected to the tactile thread S, a plurality of cocoon berries S can be easily connected with only one tactile thread S.

  In the above-described embodiment, the coconut has been described so as to be sequentially connected with a single knot S. However, according to the connecting device of the present invention, It is possible to sequentially connect other articles having an umbilical shaft portion on the top.
